Eastern Shoshone, Wind River, and Chief Washakie
The Eastern Shoshone are a Numic-speaking people of the Great Basin and Rocky Mountains whose ancestors have lived in the interior West for thousands of years[^c1]. During the 1860s the United States negotiated two treaties with the Eastern Shoshone that established their permanent home in Warm Valley—the valley of the Big Wind River and its tributaries in present-day west-central Wyoming[^c2]. Those treaties, signed at Fort Bridger in 1863 and 1868, form the legal foundation of the Wind River Reservation and remain central to Shoshone identity and sovereignty.
The reservation's early history is inseparable from Chief Washakie, the Eastern Shoshone leader who negotiated with the United States to preserve more than three million acres in Wyoming's Wind River country for his people[^c3]. Under pressure from white settlement, gold mining, and railroad construction, the reservation later shrank through a series of land cessions, and in 1878 the Northern Arapaho were placed on the same land after being promised a reservation of their own[^c7]. Supreme Court decisions in 1937 and 1938 established compensation for the Arapaho presence and confirmed the two tribes as co-owners[^c8]. Today the reservation is one of the largest in the United States[^c4], governed by two sovereign nations—the Eastern Shoshone Tribe and the Northern Arapaho Tribe—that administer separate governmental functions across the same 2.2-million-acre land base[^c5].
Shoshone culture is carried through language, ceremony, and art. Shoshone remains the ancestral language, though its future is precarious: as of 2024 fewer than one hundred people in the Eastern Shoshone tribe spoke it fluently[^c9]. Beadwork is the best-known art form of the Wind River and Fort Hall Shoshone and Bannock peoples, an enduring tradition that has evolved over time[^c6]. Geometric designs gave way to floral patterns and, in the postwar era, to the Shoshone Rose, a motif closely associated with Eastern Shoshone identity and the family of Chief Washakie. Contemporary beaders such as Antonia His Law continue to teach and demonstrate the craft within families[^c11], while Reba Jo Teran, an Eastern Shoshone beadworker and saddle maker, has practiced for 58 years and reconstructed early floral styles from historical photographs[^c23]. Joanne Brings Thunder, a granddaughter of the regalia maker Eva McAdams, carries the Washakie family tradition into painting, ledger art, and design[^c24]. Eastern Shoshone artists including Talissa Abeyta bring its visual language into public art and museum commissions[^c12]. The Shoshone also maintain the [[history/buffalo-in-shoshone-life|buffalo]] restoration that began in 2016; by the end of 2024 more than 220 buffalo roamed the reservation[^c22].
The reservation today faces interconnected questions of water, health care, governance, and economic development. The tribes hold headwater rights under the 1868 treaty to all water within the reservation, a claim sharpened by drought and the retreat of mountain glaciers[^c10]; in May 2026 tribal, university, and legal experts convened a Wind River Water Forum at Fort Washakie to address management and storage[^c21]. The Eastern Shoshone also advanced an Indian Health Service joint-venture clinic estimated to cost $116.4 million[^c20]. Tribal politics were contested in 2026: on January 10 a quorum of the General Council voted to replace the six-member Eastern Shoshone Business Council[^c15], but on September 14 the Wind River Tribal Court held that the petition for that meeting failed to satisfy the tribe's Election Ordinance[^c19]. The year also brought a religious-freedom confrontation when a non-Native pastor denounced the Sun Dance as idolatry; the two tribal governments asked the church to leave and adopted a registration system requiring their approval of nontribal organizations[^c16]. Against these disputes, intertribal partnerships expanded food sovereignty through the Sweetgrass Food Lodge[^c14], a response to a documented crisis in which 65 percent of Native American households experience food insecurity, about ten times the national average[^c18]. The Shoshone Business Council, describing its people as the Sosonrih, framed major decisions—including on water, housing, energy, and data centers—as matters requiring General Council review and long-term stewardship[^c17].
